Description

Mould structure with controllable wire position and wire bounce

This creation is related to the mold structure of a wire bomb, especially a mold structure with a controllable wire position.

Press, general speakers include woofer, midrange, and tweeter. These three units are responsible for different frequencies; most speakers work on the same principle. Like a typical moving coil speaker, when current flows through the wire to the voice coil, an electromagnetic field is generated. Since this electromagnetic field is at right angles to the magnetic field of the permanent magnet on the horn, the movable coil is forced to move in the gap; the mechanical force generated by this movement causes the paper plate attached to the voice coil to vibrate vertically and up and down. The air is made to vibrate, and the audio is transmitted to the human ear to achieve the purpose of restoring the sound for human listening, and realizing the conversion of electric energy into sound energy.

However, because the damper in the horn is connected to the voice coil, and the main function of the damper is to suspend the voice coil and drum paper, its structure is mostly concentric circles and the cross section is wavy. The elastic wave can support the voice coil and the drum paper, so the quality of the elastic wave can directly affect the amplitude of the drum paper and affect the sound quality of the speaker.

In addition, the current wire bomb includes a body and a plurality of wires, which are fixedly combined with the body through at least one wire, and one end of the wire is connected to the voice coil, and the other end is connected to the input terminal. The traditionally used shaped wire elastic wave mainly uses cotton cloth as the basic material. The cotton cloth is soaked in liquid synthetic resin so that the fibers of the cotton cloth absorb the synthetic resin. After the cotton cloth absorbing the synthetic resin is dried and hardened, it is further formed into plurals. The mold is heated, pressurized, and cut to form a wire elastic wave with ring-shaped ripples on the surface.

However, during heating and pressure forming, the hot pressing surface of the mold and the outer ring surface of the hot pressing surface will also heat the wires; this processing procedure will cause damage to the wires, and The wires are mostly twisted or braided by a plurality of metal wires; the outer ring surface formed by the hot pressing is not provided with other protective structures or reserved space, so it will cause damage to the adjacent ends of the wire. Serious; Moreover, the mold does not have a structure for clamping the ends of the wire to prevent the misalignment caused by the shrinkage of the cloth and the wire during hot pressing.

Therefore, after a long-term vibration of the wire elastic wave, the damage generated during the forming and the misalignment of the wire will cause the wire to deform as a whole, and even the wire may break.

Therefore, the creator of this case, after observing the above-mentioned deficiencies, came into being.

The main purpose of this creation is to provide a mold structure with a controllable wire position and wire bounce. Through a specific structure in the mold, it can effectively solve the problem of horn vibrating plate (also called bounce) in the manufacturing process. When heating and pressurizing, it balances the shrinkage stress of the cloth material and prevents the wire from being dislocated or deformed, loosened or damaged due to heating.

The wire protection grooves are located on both sides of the positioning protrusion; and a second mold having A forming surface, the forming surface is concavely provided with a positioning groove on the positioning protrusion, the forming surface has a forming wave portion, and the forming wave portion is provided with two wire positioning grooves corresponding to the wire protection grooves. The positioning groove is located on both sides of the positioning groove.

Preferably, the central positions of the compressed wave portion and the shaped wave portion respectively have a circular area.

Preferably, the positioning protrusion is located at the center of the circular area of the pressed wave portion, and the positioning groove is located at the center of the circular area of the shaped wave portion.

Preferably, the two wire limiting channels are continuous wavy, and the wire limiting channels are linear at the circular area.

The mold structure provided by this creation with controllable wire position and wire elastic wave is mainly used for the structural characteristics of the positioning protrusion of the first mold and the positioning groove of the second mold in the hot pressing process of the elastic wave. , So that this creation can effectively solve the problem of misalignment or deformation and looseness due to heat when the wires in the previous technology in the manufacturing process are heated and pressurized; in addition, the mold structure of this creation can achieve The utility of the whole line.
